crypto: tgr192 - fix unaligned memory access
[ Upstream commit f990f7fb58ac8ac9a43316f09a48cff1a49dda42 ] Fix an unaligned memory access in tgr192_transform() by using the unaligned access helpers. Fixes: 06ace7a9bafe ("[CRYPTO] Use standard byte order macros wherever possible") Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Sasha Levin <sashal@kernel.org>
